Technical Field

[0001] This invention relates to the field of display technology, and more specifically to display devices. Background Technology

[0002] The display driving circuit in the display device drives the pixel circuit to control the display panel to display images. However, if the amplitude of the signal transmitted by the signal line in the display panel changes from a small value to a large value, or from a large value to a small value, it will be coupled to other signal lines, thus affecting the amplitude of the transmitted signal and reducing the reliability of the display device. Summary of the Invention

[0003] The purpose of this invention is to provide a display device that solves the problem of low reliability in the operation of existing display devices due to the influence of signal amplitude changes on the amplitude of other signals.

[0004] This invention provides a display device, comprising:

[0005] The display panel includes multiple data lines and multiple sub-pixels. Each data line is electrically connected to the corresponding multiple sub-pixels. The multiple data lines are used to transmit corresponding multiple first data signals during each display period and to transmit second data signals during the blanking period after each display period. The display panel includes a first area and a second area. The multiple data lines include at least one first data line located in the first area and at least one second data line located in the second area.

[0006] A source driver, electrically connected to multiple data lines, is used to transmit corresponding multiple first data signals to the multiple data lines respectively during each initial display period. The two initial display periods of the two first data signals output by the source driver to the sub-pixels in the same row include an initial non-overlapping period. The two display periods of the two first data signals input by the first data line and the second data line to the sub-pixels in the same row include a non-overlapping period.

[0007] In some embodiments, the sum of each display period and the corresponding blanking period is the row period of the sub-pixel in the corresponding row;

[0008] The first data line and the second data line are input to the same row of the sub-pixel at the same time interval for the two first data signals and the two second data signals of the same row.

[0009] The start times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are the same;

[0010] The end times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are different.

[0013] The duration of the display period of the first data signal input to the first data signal of the sub-pixel in the same row via the first data line is greater than the duration of the display period of the first data signal input to the sub-pixel in the same row via the second data line.

[0014] In some embodiments, the sum of each display period and the corresponding blanking period is the row period of the sub-pixel in the corresponding row;

[0015] The duration of the two first data signals and two second data signals input to the sub-pixel in the same row is the same for the two row time periods.

[0016] The duration of the two display periods of the two first data signals input to the sub-pixel in the same row by the first data line and the second data line is the same;

[0017] The start times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are different;

[0018] The end times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are different.

[0019] In some embodiments, the distance between the first region and the center line is greater than the distance between the second region and the center line;

[0020] The start time of the display period of the first data signal input to the first data signal of the sub-pixel in the same row via the first data line is earlier than the start time of the display period of the first data signal input to the sub-pixel in the same row via the second data line.

[0021] Embodiments of the present invention also provide a display device, including:

[0022] The display panel includes multiple data lines and multiple sub-pixels. Each data line is electrically connected to the corresponding multiple sub-pixels. The multiple data lines are used to transmit multiple first data signals respectively during each display period and to transmit second data signals during the blanking period after each display period. The display panel includes a first area and a second area. The multiple data lines include multiple first data lines located in the first area and multiple second data lines located in the second area.

[0023] A source driver is used to output multiple of the first data signals during each initial display period;

[0024] Multiple connection lines, each of which is electrically connected between the source driver and the corresponding data line, the multiple connection lines include a first connection line electrically connected to the first data line and a second connection line electrically connected to the second data line, the compensation resistance value of the first connection line and the horizontal distance between the first connection line and the source driver, and the compensation resistance value of the second connection line and the horizontal distance between the second connection line and the source driver are all negatively correlated;

[0025] The relationship between the compensation resistance value of the first connection line and the horizontal distance between the first connection line and the source driver is different from the relationship between the compensation resistance value of the second connection line and the horizontal distance between the second connection line and the source driver. The two display periods of the two first data signals input to the sub-pixel of the same row by the first data line and the second data line include non-overlapping periods.

[0026] In some embodiments, the sum of each display period and the corresponding blanking period is the row period of the sub-pixel in the corresponding row;

[0027] The first data line and the second data line are input to the same row of the sub-pixel at the same time interval for the two first data signals and the two second data signals of the same row.

[0028] The start times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are the same;

[0029] The end times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are different.

[0030] In some embodiments, the sum of each display period and the corresponding blanking period is the row period of the sub-pixel in the corresponding row;

[0031] The duration of the two first data signals and two second data signals input to the sub-pixel in the same row is the same for the two row time periods.

[0032] The duration of the two display periods of the two first data signals input to the sub-pixel in the same row by the first data line and the second data line is the same;

[0034] The end times of the two display periods of the two first data signals input to the sub-pixel in the same row of the first data line and the second data line are different.

[0035] This invention provides a display device based on multiple data lines used to transmit corresponding first data signals during each display period and to transmit second data signals during blanking periods after each display period. The multiple data lines include at least one first data line located in a first region and at least one second data line located in a second region. The source driver is configured to output two first data signals to the same row of sub-pixels during two initial display periods including an initial non-overlapping period. This ensures that the two display periods of the first data signals input by the first data lines and second data lines to the same row of sub-pixels include non-overlapping periods. By differentiating the voltage transition times of the data signals transmitted by the data lines in different regions, the energy of noise caused to other signals is dispersed, improving the reliability of the display device.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] In the description of this invention, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified; "electrical connection" indicates that the two are conductive, and is not limited to a direct or indirect connection.

[0046] Furthermore, it should be noted that the accompanying drawings only provide structures and steps closely related to the present invention, omitting some details less relevant to the invention. The purpose is to simplify the drawings and make the inventive points immediately apparent, not to indicate that the actual device is identical to the one shown in the drawings. Figure 1 It is identical, but this is not a limitation of the actual device.

[0047] The present invention provides a display device, which may include, but is not limited to, the following embodiments and combinations thereof.

[0048] In some embodiments, combined with Figures 1 to 7As shown, the display device 100 includes: a display panel 20, including multiple data lines (DL1 to DLm) and multiple sub-pixels P, each of the data lines (DL1 to DLm) being electrically connected to a corresponding plurality of sub-pixels P, the multiple data lines (DL1 to DLm) being used to transmit corresponding multiple first data signals respectively during each display active time period, and during each display active time period... The blanking period Standbytime following the time transmits the second data signal; the source driver 30, electrically connected to the multiple data lines (DL1 to DLm), is used to transmit the corresponding multiple first data signals to the multiple data lines (DL1 to DLm) respectively during each initial display period, and to transmit the second data signal to the multiple data lines (DL1 to DLm) during the initial blanking period following each initial display period; wherein, the display panel 20 includes a first area A1 and a second area A2, the multiple data lines (DL1 to DLm) include at least one first data line located in the first area A1 and at least one second data line located in the second area A2, the two initial display periods of the two first data signals output by the source driver 30 to the two sub-pixels P in the same row include an initial non-overlapping period, so that the two display periods Active time of the two first data signals input by the first data line and the second data line to the two first data signals of the two sub-pixels P in the same row include a non-overlapping period Nov.

[0049] Among them, such as Figure 3 As shown, the display panel 20 can be, but is not limited to, an organic self-emissive display panel, an inorganic self-emissive direct-view display panel, or a liquid crystal display panel. The display device 100 may also include a gate driver 40 and a timing controller 50 electrically connected to the gate driver 40 and the source driver 30. The gate driver 40 can be a gate driving circuit located on the substrate of the display panel 20 or a chip disposed independently of the display panel 20. Figure 3 The latter is illustrated here. The timing controller 50 can provide at least a clock signal CK to the gate driver 40, and the gate driver 40 can generate multiple gate signals based on the clock signal CK. The timing controller 50 can provide at least an image signal to the source driver 30, and the source driver 30 can generate multiple data signals based on the image signal.

[0050] For ease of explanation, this example uses an array of multiple sub-pixels P arranged in n rows and m columns (n ​​and m are both positive integers). Each gate line (each of GL1 to GLn) is used to transmit a corresponding gate signal gate to the sub-pixel P in the corresponding row. The gate pulse in the gate signal gate is used to control the sub-pixel P in the corresponding row to turn on. Multiple rows of sub-pixels P are turned on sequentially under the control of multiple gate turn-on signals gate (multiple gate pulses in them). Each data line (each of DL1 to DLm) is used to transmit a data signal data to the sub-pixel P in the corresponding column. Each data signal data includes multiple first data signals (in the active time period) corresponding to the corresponding multiple sub-pixels P, and a second data signal (in the standby time period) located after each first data signal. The multiple data signals data are configured so that when each row of sub-pixels P is turned on, the multiple data lines (DL1 to DLm) can transmit the corresponding multiple first data signals to the multiple sub-pixels P in the corresponding row respectively.

[0051] like Figure 8 As shown, there can be multiple clock signals CK. Each clock signal CK can be used to generate multiple corresponding gate signals. The time periods of the multiple gate pulses of these multiple gate signals can be the same as the time periods of the multiple clock pulses in the clock signal CK. That is, each clock pulse can control the corresponding row of sub-pixels P to turn on. Here, we take the data signal data transmitted by one of the data lines (DL1 to DLm) and the multiple clock pulses in the same clock signal CK acting on multiple rows of sub-pixels P as an example, where there can be a gap of two rows of sub-pixels between adjacent ones. The data signal data can include multiple first data signals (second data signals are not shown here) corresponding to multiple sub-pixels P in the corresponding column. Then, the above-mentioned "two rows of sub-pixels P" can be controlled to turn on by the clock pulses of the other two clock signals CK respectively. Each row of sub-pixels P turns on during the time period of the clock pulse corresponding to the corresponding clock signal CK, and the multiple data signals data respectively transmit the corresponding first data signals to multiple columns of sub-pixels P.

[0052] Furthermore, such as Figure 2 As shown, the display device 100 may also include a touch panel 10 disposed opposite to the display panel 20. For example, the display device 100 may be an external touch screen. However, while the touch driving circuit of the external touch screen is performing touch detection, the display driving circuit also drives the display panel to display the image. Therefore, some signal transitions in the display screen may be coupled to the touch electrodes in the touch screen, increasing the risk of touch misjudgment and reducing the reliability of the touch function of the external touch screen.

[0053] Specifically, since the potentials of two adjacent first data signals in the data signal data may have a large difference, that is, the amplitude of the data signal data will change from a smaller value to a larger value, or from a larger value to a smaller value (called a jump), and the potential of each clock signal CK will also jump due to multiple clock pulses (that is, the amplitude of each clock signal CK will change from a smaller value to a larger value, or from a larger value to a smaller value), the above two potential jumps will generate the first noise noise1 and the second noise noise2 respectively. Since the touch electrodes in the touch panel 10, which is opposite to the display panel 20 in the external touch screen, also need to work during this process, and there is coupling capacitance between multiple gate lines (GL1 to GLn) and multiple data lines (DL1 to DLm) and the touch electrodes, the first noise noise1 and the second noise noise2 will increase the risk of touch misjudgment of the external touch screen.

[0054] like Figure 4 As shown, the sum of each display period (Active time) and the corresponding blanking period (Standby time) is the line time of the corresponding row of sub-pixels P. Each frame may include multiple line times corresponding to multiple rows of sub-pixels P. As discussed above, the energy of the first noise 1 is concentrated at the alternation time between the display period (Active time) and the blanking period (Standby time).

[0055] Combination Figure 3 and Figure 5 As shown, a center line L can be defined that passes through the center point of the display area of ​​the display panel 20 and is parallel to the column direction. In the row direction, the display area can be divided into multiple regions. These regions may include two first regions Z1 symmetrical about the center line L, two second regions Z2 symmetrical about the center line L, two third regions Z3 symmetrical about the center line L, and a fourth region Z4 bisected by the center line L. The distances from the first region Z1 to the fourth region Z4 to the center line L decrease sequentially. It should be noted that the method of dividing the multiple regions (including the number and position) may differ from... Figure 5 The division method in Figure 5 This is just one example. In this embodiment, the first region A1 and the second region A2 can be two regions that are equidistant from the center line L or unequal in distance. Here, we only use the example of the first region A1 and the second region A2 being the first region Z1 and the third region Z3, respectively.

[0056] As discussed above, under normal circumstances, since multiple sub-pixels P in the same row are turned on at the same time, the multiple display periods active times of the multiple first data signals corresponding to the multiple sub-pixels P transmitted by multiple data lines (DL1 to DLm) are the same. However, in this embodiment, it is considered that this will cause the potential of the multiple data signals data transmitted by multiple data lines (DL1 to DLm) to jump when transmitted to each row of sub-pixels P, causing the energy of the first noise 1 to be concentrated and distributed as horizontal lines, which has a significant impact on the potential of the touch electrodes in the corresponding area of ​​the touch panel 10.

[0057] Based on the above considerations, such as Figure 6 and Figure 7 As shown, this example illustrates how multiple display periods (Active times) and multiple blanking periods (Standby times) of multiple data signals (data) transmitted from multiple data lines (DL1 to DLm) in the same area are all the same. In this embodiment, the Active times of two display periods of two first data signals (data1 in the first area and data3 in the third area, respectively) input to the same row sub-pixel P by the first data line located in the first area A1 (e.g., the first area Z1) and the second data line located in the second area A2 (e.g., the third area Z3) are set to include a non-overlapping period (nov). That is, the start time and / or end time of the two first data signals corresponding to the same row sub-pixel P in the first area data signal data1 and the third area data signal data3 are different. This makes the corresponding noises in the first area noise 11 and the third area noise 13 at different times, which can make the energy distribution of multiple noises more dispersed, so as to avoid causing greater interference to the touch electrodes at specific positions in the touch panel 10, thereby improving the reliability of the touch function of the display device 100.

[0058] It should be noted that, for the non-touchscreen display device 100, by setting the start time and / or end time of the two first data signals corresponding to the same row sub-pixel P in the first area data signal data1 and the third area data signal data3 to be different in this embodiment, the energy distribution of multiple noises can be more dispersed. This can also avoid causing significant interference to the amplitude of signals transmitted by other signal lines inside the display panel 20, thereby improving the reliability of the operation of the display device 100.

[0059] Furthermore, the active time of multiple display periods of multiple data signals (data) transmitted by multiple data lines (DL1 to DLm) in different areas can be set to have non-overlapping time periods (nov). This allows the noise generated by different data signals in different areas corresponding to the same row of sub-pixels P to be distributed at different horizontal positions, further reducing interference to the touch electrodes at specific locations in the touch panel 10. Figures 5 to 7 As shown, this example illustrates that for two regions (e.g., two first regions Z1, two second regions Z2, two third regions Z3, and two fourth regions Z4) that are equidistant from the center line L, the active times of multiple display periods are the same, and the standby times of multiple blanking periods are the same. The active times of two display periods corresponding to the same row sub-pixel P of any two of the first region data signals data1 to the fourth region data4 corresponding to the first region Z1 to the fourth region Z4 can be set to have non-overlapping periods nov.

[0060] Specifically, such as Figure 3 As shown, in this embodiment, the source driver 30 is directly configured to generate multiple initial data signals. Each initial data signal includes the first data signal and the second data signal arranged alternately. The two initial display periods of the two first data signals output by the source driver 30 to the same row of sub-pixels P include the initial non-overlapping period. If the transmission path loss corresponding to different regions is of a similar degree, it can be considered that the multiple display periods of the multiple data signals data transmitted by multiple data lines (DL1 to DLm) are delayed by a certain period compared to the multiple initial display periods. However, it is still possible to ultimately realize that the two display periods of the two first data signals input to the same row of sub-pixels P by two data lines (selected from DL1 to DLm) in different regions also include the non-overlapping period nov. The non-overlapping period nov can be considered to be caused by the initial non-overlapping period. Even if the transmission path loss corresponding to different regions is different, the non-overlapping period nov can be formed by appropriately setting the initial non-overlapping period.

[0061] In other embodiments, combined with Figure 3 and Figure 4As shown, the display device 100 includes: a display panel 20, including multiple data lines (DL1 to DLm) and multiple sub-pixels P, each of the data lines (DL1 to DLm) being electrically connected to the corresponding multiple sub-pixels P, the multiple data lines being used to transmit corresponding multiple first data signals during each display period (Active time) and to transmit second data signals during each blanking period (Standby time) following each display period (Active time), the display panel 20 including a first area A1 and a second area A2, the multiple data lines including multiple first data lines located in the first area A1 and multiple second data lines located in the second area A2; a source driver 30, used to output multiple first data signals during each initial display period (the two initial display periods in which the source driver 30 outputs two first data signals to the sub-pixels P in the same row include or exclude the initial non-overlapping period); multiple connecting lines 60, each of the connecting lines 60 being electrically connected between the source driver 30 and the corresponding data lines, the multiple connecting lines 60 including those electrically connected to the first data lines. The first connecting line and the second connecting line electrically connected to the second data line are negatively correlated with each other. The compensation resistance value of the first connecting line and the horizontal distance between the first connecting line and the source driver are negatively correlated with each other. The relationship between the compensation resistance value of the first connecting line and the horizontal distance between the first connecting line and the source driver is different from the relationship between the compensation resistance value of the second connecting line and the horizontal distance between the second connecting line and the source driver. The two display periods of the two first data signals input to the sub-pixel of the same row by the first data line and the second data line include non-overlapping periods.

[0062] Combination Figure 3 and Figure 9 As shown, in the comparative example, the compensation resistor value R of the connecting line 60 is set to vary in the same way as the horizontal distance |d| between the connecting line 60 and the source driver 30. Figure 9 A coordinate axis is plotted with the center of the source driver 30 as the origin O. The horizontal axis d represents the relative position of the connecting line 60 and the source driver 30 it is connected to in the horizontal direction. A positive d indicates that the connecting line 60 is located to the right of the center of the corresponding source driver 30, and vice versa. Figure 9Taking the setting of two source drivers 30 as an example, it can be shown that under normal circumstances, the compensation resistance value R of the connection line 60 is directly proportional to the horizontal distance |d| between the connection line 60 and the corresponding source driver 30, and the closer the connection line 60 is to the center of the corresponding source driver 30, the larger the compensation resistance value R is. In this way, the attenuation difference caused by two connection lines 60 with different distances from the same source driver 30 to the initial data signal they receive can be reduced, so that the waveforms of multiple data signals data transmitted by multiple data lines (DL1 to DLm) in different regions can be nearly coincident on the time axis.

[0063] Based on this, combined Figure 3 and Figure 10 As shown, in this embodiment, the compensation resistance value R of the connecting line 60 corresponding to different regions can be set to vary with the horizontal distance between the connecting line 60 and the source driver 30. Based on the division of the display area into multiple regions, Figure 9 In this embodiment, all regions can have the same "change relationship" (including but not limited to the four "change relationships" k1, k2, k3, and k5 corresponding to four regions with different distances from the corresponding source driver 30). Figure 10 As shown, the above-mentioned "change relationships" (including but not limited to the above four "change relationships" k1, k2, k3 and k5) corresponding to at least two regions can also be set to be different.

[0064] Understandable. Figure 9 By setting the aforementioned "change relationship" corresponding to different regions to be the same (proportional), the attenuation difference caused by two connection lines 60 with different distances from the same source driver 30 to the initial data signal they receive can be reduced; while in this embodiment, for example... Figure 10 As shown, under the premise that the above-mentioned "change relationship" is negatively correlated in different regions, the specific values ​​of the above-mentioned "change relationship" in at least two regions are further set to be different, that is... Figure 10 The different slopes in the data signals reduce the attenuation difference caused by the two connection lines 60, which are at different distances from the same source driver 30, to the initial data signals they receive. By differentiating the slopes, the waveforms of the data signals transmitted by the data lines (selected from DL1 to DLm) in different regions are still different, so that the two display periods of the first data signals input to the sub-pixel P in the same row can still include non-overlapping periods.

[0065] In summary, whether the source driver 30 is directly set to output two first data signals to the same row sub-pixel P, including the initial non-overlapping period, or the compensation resistance value of the connecting line 60 in different regions is set to vary with the horizontal distance between the connecting line 60 and the source driver 30, it is possible to realize that the two display periods (Activetime, including the non-overlapping period nov) of the two first data signals input to the same row sub-pixel P by the data lines (selected from DL1 to DLm) in different regions can be realized.

[0066] In some embodiments, combined with Figure 3 , Figure 5 and Figure 6 As shown, the first data line (located in the first area A1) and the second data line (located in the second area A2) input to the same row of sub-pixel P have the same line time for the two first data signals and the two second data signals; the first data line and the second data line input to the same row of sub-pixel P have the same start time for the two display time active times for the two first data signals; and the first data line and the second data line input to the same row of sub-pixel P have different end times for the two display time active times for the two first data signals.

[0067] Understandably, by setting the compensation resistor values ​​of the source driver 30 and / or the connection line 60 as described above, this embodiment further limits that among the multiple data signals data that are ultimately formed, at least two regions corresponding to the same row sub-pixel P have the same line time, the same start time of the display time active time, and different end times of the two display time active times. By setting the "different end times of the two display time active times" for different regions, the time when the data signal data corresponding to the same row sub-pixel P in different regions jumps from the first data signal to the second data signal is different, thereby making the noise corresponding to the row sub-pixel P at different times, so as to disperse the energy of the noise.

[0068] Based on the above content, it can be seen that, combined with Figure 3 , Figure 5 and Figure 6As shown, at this time, the durations of the two display periods (Active time) of the two first data signals input to the sub-pixel P in the same row by the first data line and the second data line are different; the durations of the two blanking periods (Standby time) of the two second data signals input to the sub-pixel P in the same row by the first data line and the second data line are different; the distances between the first area A1 and the center line L parallel to the column direction of the display panel 20, and the distances between the second area A2 and the center line L are different.

[0069] Here, α is defined as Standby time / Line time. In other words, in this embodiment, by setting the duration of the Active time of the display period corresponding to the same row of sub-pixels P in different regions to be the same, but setting α to be different, that is, the duration of the Standby time of the blanking period corresponding to the same row of sub-pixels P in different regions is different, it is still possible to achieve different times in the data signal data of the same row of sub-pixels P in different regions when the first data signal jumps to the second data signal.

[0070] It should be noted that for two regions with different distances from the center line L, the attenuation difference caused by two connecting lines 60 with different distances from the same source driver 30 to the initial data signals they receive can be reduced by "directly setting the source driver 30 to the two initial display periods including the initial non-overlapping period of the two first data signals output to the same row sub-pixel P" and / or "setting the compensation resistance value of the connecting line 60 of different regions to be negatively correlated with the horizontal distance between the connecting line 60 and the source driver 30". In this embodiment, by further reasonably setting the specific values ​​of the initial non-overlapping period and / or negative correlation, noise energy can also be dispersed at the same time.

[0071] Furthermore, in combination Figure 3 , Figure 5 and Figure 6 As shown, the distance between the first region A1 (e.g., the first area Z1) and the center line L is greater than the distance between the second region A2 (e.g., the third area Z3) and the center line L; the duration of the display period Active time of the first data signal input by the first data line to the first data signal of the sub-pixel P in the same row is greater than the duration of the display period Active time of the first data signal input by the second data line to the first data signal of the sub-pixel P in the same row.

[0072] Understandably, since the distance between the first region A1 (e.g., the first region Z1) and the center line L is greater, the data signal α transmitted by the data line corresponding to the first region A1 can be smaller by setting the initial data signal output by the source driver 30 and / or the compensation resistor value of the connection line 60. This can reduce the attenuation difference and noise energy dispersion caused by the two connection lines 60 that are at different distances from the same source driver 30.

[0073] For example Figure 6 In this case, the α values ​​in the first region data signal data1 to the fourth region data signal data4, corresponding to the first region Z1 to the fourth region Z4, which are successively decreasing in distance from the center line L, can be set to increase successively. For example, they can be 1%, 1.2%, 1.4%, and m%, respectively, where m is greater than 1.4. That is, the duration of the display period Active time is set to decrease successively, and thus the corresponding energy in the first region noise11 to the fourth region noise14 is successively delayed.

[0074] In one embodiment, combined with Figure 3 , Figure 5 and Figure 7 As shown, the duration of the two line time periods (Linetime) of the two first data signals and two second data signals input to the sub-pixel P in the same row is the same for both the first data line and the second data line; the duration of the two display time periods (Active Time) of the two first data signals input to the sub-pixel P in the same row is the same for both the first data line and the second data line; the start time of the two display time periods (Active Time) of the two first data signals input to the sub-pixel P in the same row is different for both the first data line and the second data line; and the end time of the two display time periods (Active Time) of the two first data signals input to the sub-pixel P in the same row is different for both the first data line and the second data line.

[0075] Similarly, by setting the compensation resistor values ​​of the source driver 30 and / or the connection line 60 as described above, this embodiment further limits that among the multiple data signals data that are finally formed, at least two regions corresponding to the same row sub-pixel P have the same line time, different start times of display time active time, and different end times of display time active time. While ensuring that the duration of the two display time active times is equal and α is equal, it is also possible to make the time when the data signal data corresponding to the same row sub-pixel P in different regions jump from the first data signal to the second data signal and the time when the data signal data jumps from the second data signal to the first data signal is different, so that the noise corresponding to the row sub-pixel P is at a different time, thereby dispersing the energy of the noise.

[0076] Based on the above discussion, it can be seen that, combined with Figure 3 , Figure 5 and Figure 7 As shown, the time interval between the start times of the two display periods (Active time) of the two first data signals input to the sub-pixel P in the same row by the first data line and the second data line, and the time interval between the start times of the two blanking periods (Standby time) of the two second data signals input to the sub-pixel P in the same row by the first data line and the second data line, are the same; the distance between the first area A1 and the center line L parallel to the column direction of the display panel 20, and the distance between the second area A2 and the center line L are different.

[0077] Unlike Figure 6 In the illustrated embodiment, by setting the duration and α of the display period Active time corresponding to the same row of sub-pixels P in different regions to be the same, it is also possible to achieve different transition times between the first data signal and the second data signal in the data signal data of the same row of sub-pixels P in different regions. However, similarly, by further reasonably setting the specific values ​​of the aforementioned initial non-overlapping period and / or negative correlation, noise energy can also be dispersed in this embodiment.

[0078] Furthermore, in combination Figure 3 , Figure 5 and Figure 7 As shown, the distance between the first area A1 and the center line L is greater than the distance between the second area A2 and the center line L; the start time of the display period Active time of the first data signal input by the first data line to the first data signal of the sub-pixel P in the same row is earlier than the start time of the display period Active time of the first data signal input by the second data line to the first data signal of the sub-pixel P in the same row.

[0079] Similarly, since the distance between the first region A1 (e.g., the first region Z1) and the center line L is greater, whether by setting the initial data signal output by the source driver 30 and / or the compensation resistor value of the connecting line 60, the waveform of the data signal transmitted by the corresponding data line of the first region A1 can be earlier than that of the second region A2. This can reduce the attenuation difference and noise energy dispersion caused by the two connecting lines 60 that are at different distances from the same source driver 30 to the initial data signal they receive.

[0080] For example Figure 7 In this way, the waveforms of the data signals data1 to data4 in the first region, corresponding to the first region Z1 to the fourth region Z4, which are successively delayed by decreasing distances from the center line L, can be delayed sequentially. For example, they can be 1%, 1.2%, 1.4%, and m%, respectively, where m is greater than 1.4. That is, the duration of the display period Active time is set to decrease sequentially, and thus the corresponding energy in the noise 11 in the first region to the noise 14 in the fourth region is delayed sequentially.
